Hi I want to understand the difference between Binary Cyclic Coding blocks and BCH Coding blocks in Simulink. I have read in many books that BCH coding is a type of cyclic code (the most used cyclic code). Also a (7,4) Hamming Code is cyclic code. What is the difference if I use Cyclic Encoder and Cyclic Decoder blocks of simulink instead of BCH Encoder and BCH decoder in a communication model in simulink. I receive slightly different results. Can anybody explain why there are Cyclic Encoder and Cyclic Decoder blocks in simulink isn't cyclic encoding just a set that contains BCH, Hamming, Repeater etc. codes? Thank You!
